Application filed September 18, 1919. Serial No. 324,639.

To all whom tmag concern:

Be it known that I, CHARLES W; SMITH, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented-a newand useful Improvement in Charge-Moistening Devices.

.for Internal-Combustion Engines, of which the following is-a specification.

This invention relates .to attachments for automobiles, and more particularly to a de-' vice having communication with the engine thereof,for reduclng to a m1n1mum, carbon deposit within the cylinder, and on the valve members thereof.

A further object of' the invention is to direct the gas which collects in the crank case of the'engine, to the engine cylinders where the same is usedas fuel,-the'reby rendering the engine more powerful, with a given quantity of gas. I

A further object of the, invention is to provide a device of this character which may be 'efiiciently employed as a priming device, if so desired, to .facilitate the starting of the engine in coldweather. I

W1th the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 illustrates a side elevational view of an automobile, the same being shown as partly broken away, to disclose the relation of the invention with the engine.

Fig. 2 illustrates a front plan view of the tank used in connection with the engine,

Fig. 3 illustrates a sectional view taken on line 33 of Fig. 2. v

Fig. 4 illustrates a transverse sectional View taken on line 4-4 of Fig, 3.

Referring to the drawings in detail, the

7 reference character 5 designates the dash board of an automobile, supplied with the device forming the subject matter of the present invention.

The dash board 5, is providedwith a central bore 6. through which extends the pipe 19, which has communication with the manifold of the engine, as at'20, for supplying the engine with gas, in theevent that the device 1s to be employed as a primer.

The clash board 5 is also provided with lateral bores 9 and 10, each of which accommodates a pipe 11, which has its ends threadedas at 12, one of'said ends of one pipe be- 2 ing internally threaded to receive the threaded end 1a of the pipe15, whichhas connec tion with the water jacket of the engine, asat 16, and it will be seen that due to the connection between the pipe and water jacket, the steam, generated in the water jacket, is carried off through said pipe 15.

Specification of Letters Patent. "Paten tgd N 23,1920

The'opposite pipe, is also internally screw threaded to receive one end of the pipe 17, whlch has communication with the crank casing, as at 18, whereby the gases which ordinarily collect in the crank casing, mar

be drawn oil, and admitted to the cylinders of the engine, through pipe 19, which as shown has connection with the the engine, as at 20. I I v Each of the pipes, is in communicationthe form of a block, and is provided with a plurality of bores 22, which have connection with the respective pipes 15, 17, and 19. The block 21, is provided with an annular groove manifold of 'with a supporting: member 21, which is in 23, formed in the upper surface thereof,

which groove accommodates a packing 24:, to prevent leakage between the glass cylinder 25, which forms the body of the receptacle, the lower ends of said cylinder 25, being disposed withi'n'the annular groove 7 23, and held therein, by means of the elon" gated rod 26, having a threaded end 270perating in a threaded opening formed in the upper surface of the block 21.

Disposed on the upper. edge of the cylinder 25, is a cover 29, which is provided with an annular depending flange 30, adapt-v ed to embrace the cylinder adjacent the upsame terminating substantially intermedi ate the length of the rod, and havinga lateral portion 36 providing communication between the bore, and the cylinder 25.

A valve member 37, is provided with a reduced end 88, intersecting the bore 35, to restrict the flow of fluid through'the bore 35 formed in the rod 26.

The bores 22, extend through the block 2 21, and are provided with threaded portions their ends supported within the bores 45,

also formed in the block v21, the upper ends of said nozzles 44, being curved as indicated at a 46, whereby the flow of fluid through the nozzles,'is directed downwardly toward the bottom of the cylinder '25.

From the foregoing it is obvious that when the engine is running, the suction caused by the pistons operating in their cylinders, causes steam to be drawn through the pipe 15, and deposited within the cyl inder 25, at the same time the gases, which have collected in the crank case, are drawn into the cylinder '25, through the pipe 17, whereby the gases mingle with the steam or vapor, and are drawn into the engine, through the pipe 19, which as before stated, has connection with the manifold of the 'en gine.

If it is desired to employ the device as a primer, it is only necessary to operate the valves 41 and 42, to close the pipes leading from the crank casing, and water jacket, fill the funnel with asuflicient quantity of gasolene, to prime the engine, and allow the 7 same to flow downwardly into the cylinder of the rod, said funnel adapted to direct fluid through the rod, means for providing communication between the cylinder, crank casing, and water jacket of the engine, means for providing communication between the cylinder and manifold of the engine, whereby material is drawn from the crank casing and water jacket, into the cylinder, and discharged into the manifold of the enin In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
